A spring is a natural exit point at which groundwater emerges out of the aquifer and flows onto the top of the Earth's crust (pedosphere) to become surface water. It is a component of the hydrosphere, as well as a part of the water cycle. Springs have long been important for humans as a source of fresh water, especially in arid regions which have relatively little annual rainfall.
On an average day nearly 303 million US gallons (1,150,000 m3) of water flow from Big Spring in Missouri at a rate of 469 cubic feet per second (13.3 m3/s).
